If you encounter issues using the speaker with your phone or tablet, or you want to remove all previous Bluetooth pairings from the speaker, it may be necessary to 'factory reset' the speaker.

How to reset
First, remove or forget the speaker from the list of paired Bluetooth devices in the settings of the phone or tablet.
Then, with the speaker powered on, press and hold the Volume + and Play buttons simultaneously for 3 seconds until the unit turns off.
The speaker has now been restored to factory default settings.
